Word clouds

This feature might be more useful (to me anyway) if you could limit the number of words to display.

For example if I could see the top 50 and then when I eliminate a word by ctrl-clicking on it, move the 51st word into the display. Keep moving a less frequent word in every time one is eliminated but maintain 50 ( or some number to be specified) showing in the window.

This would be especially useful for looking at a book or a large portion of scripture.
